Title: Throttle controller
Inventor: TERASAWA TEI
IPC: F02D41/22
Filed: 1991-02-21
Abstract: PURPOSE:To control electrification of an electromagnetic coil in response to a detected result by detecting a relative displacement between a member which interlocks to an acceleration operation mechanism and a member which interlocks a throttle valve with a simple construction without damaging a detector. CONSTITUTION:An operation plate 60 is rotated around a shaft coaxial with a throttle shaft 12 in response to operation of an acceleration pedal 7. A driven member 70 which attaches to both end faces of first and second contact end faces is driven in response to differential movement between an operation plate 60 and a plate holder 50. When a rotational displacement of the plate holder 50 in relation to the operation plate 60 is more than a specified rotational angle, a limit switch 80 is operated via a driven member 70 in response to the driven operation, and current feed to an electromagnetic coil 20 is stopped. Consequently, a connection condition between a clutch plate 40 and a rotor 30 is released.

Title: Reducing method for center segregation of continuously cast steel slab
Inventor: OKAMOTO NOBORU
IPC: B22D11/10
Filed: 1979-04-24
Abstract: PURPOSE: To reduce center segregation chemcally and thermodynamically in place of conventional physical means and achieve the improvement in steel quality at the same time by continuously casting the molten steel which is so desulfurized that the content of S(%) is specified in accordance with the content of C(%).  
     CONSTITUTION: The molten steel having been subjected to such a desulfurization treatment that the content of S(%) becomes (C×S)≤1.8×10 -3  (preferably S< 0.005%) in accordance with the content of C (preferably 0.35W0.65%) is continuously cast. If the S-content is lowered, liquidus line temperature rises and the accumulation of the thickened components at the solidification front is eased, by which the center segregation comprising primarily of segregation of C is reduced, and segregation of S is also reduced. Hence, the peel cracking at the central part of the thickness is considerably reduced and the results of macro-segregation becomes good as well. This method makes it possible to prevent the increase in inclusions and the occurrence of nozzle clogging at the conventional low-temperature casting and prevent the decrease in productivity and the increase in machine load at the low-speed casting.

Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To recover a communication error caused by fading or interruption of a radio wave or the like efficiently. SOLUTION: A communication error detection means 1 of the radio communication system detects a packet causing a communication error and allows a re-transmission means 4 to send the packet after a prescribed time set in a re-transmission timing setting means 3.
